This study aims to propose a documentation model for the two official, state-sponsored art competitions: the Joseon Art Exhibition (1922–1944) and the National Art Exhibition (1949-1981). The documentation methodology that focuses on “contexts” such as art competitions, works, and artists should be applied, as this approach enhances both the clarity and utility of the collected data. This study comprises three primary components. First, through a literature review, the study examines the historical significance of these competitions in Korean modern and contemporary art history while establishing the necessity of their documentation. Second, it investigates potential repositories and analyzes the status of primary sources related to these competitions. Third, this study proposes a documentation model for the two official competitions from the perspective of laying the foundation for Korean modern and contemporary art archives. This model is characterized by supporting dynamic, scalable, and sustainable documentation. It is hoped that the documentation model for the two official art competitions will be implemented, laying the foundation for comprehensive archives of Korean modern and contemporary art.
